The martial arts training dummy is an anthropomorphic mannequin formed of substantially solid resilient material, such as rubber or plastic, and having a specific gravity approximating that of the human body. The limbs at the shoulders, hips, and knees are pivotally attached to their adjacent components, the joints having sufficient friction to hold a set position after adjustment. The training dummy is devoid of external support and, while being incapable of standing erect, it may be positioned on hands and knees or on its back for practicing various ground moves and holds in various martial arts. The upper arms, thighs, and lower trunk are hollow and have springs installed therein. The springs have bending resistances approximately equal to the forces required to break bones of the corresponding areas of the human body. A limb suffering a simulated breakage will return to its original position without damage for continued practice.
